What to do with suspect water
Undoubtedly, the simplest, easiest and most practical treatment is boiling for approximately 10 minutes, as suggested by most authorities. Boiling does not assist with anything dissolved, including blue-green algae toxins, most chemicals and heavy metals.
Beyond boiling, most medical and scientific authorities which have investigated water-treatment approaches have concluded that the following treatments are most effective:
- iodine-based chemical treatment for giardia, E. coli, bacteria, viruses and protozoa, in conjunction with;
- activated-carbon filtration, which is generally effective against toxic blue-green algae, of benefit against chemical and heavy-metal contamination, and of some benefit against bacteria, viruses, etc.
